Diaphragms and pressure capsules

Diaphragms and pressure capsules

Pressure capsules, diaphragms and membrane box assemblies, organised by design and material. Depending on the version, measuring ranges extend from 0 … 0.2 kPa to 0 … 2500 kPa and diameters from Ø 12.4 mm to Ø 130 mm.

• Stainless steel: pressure capsules in 316L, six sizes, Ø 48 … 114 mm
• Copper: pressure capsules in CuBe or bronze, eight sizes, Ø 38 … 114 mm
• Double membrane: eight sizes, Ø 38 … 114 mm, with a displacement of 2.2 … 3 mm
• Pressure gauge measuring diaphragm for diaphragm pressure gauges, up to 0 … 2500 kPa
• Isolation diaphragm: 26 models, Ø 12.4 … 110 mm, diaphragm thickness 0.025 … 0.1 mm
• Stainless steel membrane box assembly: Ø 56.5 and 72 mm
• Monolithic membrane box assembly: Ø 45, 56.5 and 72 mm, up to 0 … 160 kPa
• Overpressure single-piece diaphragm assembly: Ø 45, 56.5 and 72 mm, connection M10 × 1

Selection and quotation

Size, measuring range and material define the version; for most designs the connection thread is M5 or customised. Describe your application in the quotation form. More on design and materials under pressure capsules and diaphragms.
